Series premieres sometime this year. The new PV is here. P.A. Works will be heading the production. Synopsis of the game from the ANN article:

Players take on the role of Sakuna, a proud yet lonely harvest goddess who is banished to a dangerous island with a group of outcast humans. Sakuna tames the island by defeating demons using farm tools as weapons while chaining attacks with her “celestial scarf,” a magical item that allows her to grapple distant enemies and platforms.
